Abstract

Procedeu de obtinere a fierului spongios, conform inventiei, prevede reducerea directa a minereului oxidic de fier într-un reactor vertical, ce cuprinde o zona superioara de reducere si o zona superioara de reducere si o zona inferioara de racire a minereului redus, în care minereul circula în contracurent, în zona de reducere cu gaze reducatoare cu continut ridicat de CO si H2 preîncalzite la 750....1000 degree C si care dupa evacuare din reactor, conditionare si preîncalzire se recircula formînd o bucla închisa a circuitului gazelor de reducere si respectiv în zona de racire cu gaze de racire, cu continut de carbon, care se introduc în reactor la capatul inferior al zonei de racire si si dupa trecerea prin zona de racire mentionata si racirea fierului spongios, se elimina pe la partea superioara a acesteia se racesc si se recircula formînd de asemenea o bucla închisa a circuitului gazelor de racire.....
